Is LC studio SD card shield reasonable?

Other Hardware Storage
1

Hello

I have a project that take multiple analog signals from multiple sensors

and store the data to SD card.

I can found SD card shield from LC studio and they sell it on Ebay.

I cannot find those on Mouser or Sparkfun, which are more reasonable electronic vendors.

Does the LC studio sd shield do their job reasonably?

One more question,

Like I say, I have to get multiple analog data from multiple analog channels (10 or more)

and store the data to SD card.

Does anyone have an experience to do that?

It would be glad if I can get some help from you guys.

Thank you~!

There have been many problems with the LC Studio SD module. This module does not have the correct 5V to 3.3V SPI level shifters required for 3.3V SD cards. Some cards work but this module stress SD cards and is be unreliable.

Than, can you suggest any sd shield for my Mega 2560?

If you want a shield you could try this http://www.ebay.com/itm/TF-Card-SD-Expansion-Board-Shield-Stackable-Module-Building-Block-For-Arduino-/141439314893.

I have used it on a Mega 2560. It has the ISP style SPI connector, a level shifter, and a 3.3V regulator.

If you just want an SD module, make sure it has an IC level shifter like this module http://www.ebay.com/itm/Micro-SD-Storage-Board-Mciro-SD-TF-Card-Memory-Shield-Module-SPI-For-Arduino-SY-/221595066302
I have used this module but some versions of this module may not share the SPI bus with other devices. Some models drive MISO even when CS is high. So don't buy this if you have other SPI devices.

This is an excellent but expensive module http://www.adafruit.com/product/254http://www.adafruit.com/product/254

Thanks for your recommendation.

I am kinda new to this, I cannot quite understand what you suggested.

I may need some study for that.

I like the last one you suggested. Does it work with Mega 2560? Have you tried?

If it works I would like to purchase it.

The Adafruit microSD adapter works well with Mega 2560. You just need to connect to these pins.

If you have a Mega, the pins are different! You'll want to use digital 50 (MISO), 51 (MOSI), 52 (SCK)

You can use any pin for CS, chip select. You just need to call SD.begin(csPin) with the pin number that you use.
